Find out the correct number of bones in the human skull (i.e. cranial bone, facial bone, and middle ear bone, respectively)
1 14,8 , and 3
2 6,8 , and 1
3 14,8 , and 1
4 8,14 , and 6
Explanation:
The skull is composed of two sets of bones - cranial and facial, that totals to 22 bones. Cranial bones are 8 in number. They form the hard protective outer covering, cranium for the brain. The facial region is made up of 14 skeletal elements which form the front part of the skull. A single U-shaped bone called hyoid is present at the base of the buccal cavity and it is also included in the skull. Each middle ear contains three tiny bones - Malleus, Incus and Stapes, collectively called Ear Ossicles.

The cervical vertebra called axis provides head with sideways rotation. Reason for this is
1 It contains odontoid process that fits into the odontoid canal of atlas
2 It is joined through elastic pads of fibrocartilage with other vertebrae, which provide mobility
3 It is fused with 1st vertebra atlas
4 It is articulated to skull through occipital condyles
Explanation:
The joint between the atlas and axis is a pivot type of joint. The axis has the odontoid process around which the atlas rotates. It allows the head to turn from side to side. It is also called the atloaxoid joint. The ligaments that serve to support and strengthen this joint are called the capsular; anterior and posterior atlantoaxial; and transverse ligaments.

The vertebrae, which bears the whole weight of the skull is
1 Axis
2 Sacral
3 Cervical
4 Atlas
Explanation:
According to Greek mythology, their one God Atlas supports the earth. If the skull can be considered as the globe (earth), then first vertebra which bears whole of its weight can be regarded as Atlas. It is named on this basis only.

Number of floating ribs in human body is
1 6 pairs
2 5 pairs
3 3 pairs
4 2 pairs
Explanation:
There are 2 pairs of floating ribs in human body. There are 12 pairs of ribs, the first 7 pairs are called true ribs (anterior ends directly attached to sternum). The 8th, 9th, 10th pair of ribs are called false ribs (indirectly attached to sternum). The last 2 pairs (11th and 12th pair) are floating ribs, their anterior end is not attached to sternum, these are floating and protect the kidney.
